Title: Gasification process of solid carbonaceous material
Inventor: OKAMURA SHOZO
IPC: C10J3/57
Filed: 1981-08-07
Granted: 1984-07-17
Abstract: Abstract:      The invention provides a process for gasification of solid carbonaceous material such as coal.  In this process the powdered coal is top-blown onto a molten iron bath located in a furnace through a non-submerged lance toward a hot spot formed by means of a jet of oxygen and steam also top-blown through a non-submerged lance.  The coal is blown by means of a carrier gas, and flux is optionally blown toward the hot spot or added to the furnace in lump form. The ratio L/Lo of the depression depth L of the molten iron bath to the molten iron bath depth Lo is maintained within the range of 0.05 to 0.15, and the blowing velocity of the solid carbonaceous material is maintained within the range of 50 to 300 m/sec so as to  suppress the formation of an adhered mass in the furnace.  A stirring gas is blown through a bottom nozzle to stir  the molten iron bath.  In this way, coal gasification can be achieved with high efficiency for long production runs.

Abstract: A DEVICE FOR CONNECTING FLANGED PIPES            Abstract of the Disclosure The invention relates to a device for connecting flanged pipes.          For this purpose, a multiple-section clamp is mainly used which includes inwardly protruding flanges engaging beyond the collars of the pipe ends.  An annular profiled seal forms an approxi-mately U-shaped hollow profile with the shanks which are formed as sealing lips and which abut against the peripheral surfaces of the collars.  The assembly of the profiled seal is difficult.  The sealing effect is often impaired by the peripheral surfaces of the collars being no longer sufficiently even and smooth.  These draw-backs are removed by the invention such that the profiled seal has inner profiled section extending between the faces of the collars and that the outer surfaces of the outer profiled section surroun-ding the peripheral surfaces of the collars are reinforced at a guide ring.  Thus, the particular sealing region is disposed be-tween the faces of the collars.  The assembly is simplified by the reinforced outer profiled section of the profiled seal.

Abstract: TAMPER-ALERTING HYPODERMIC SYRINGE               ABSTRACT OF THE DISCLOSURE         The inside surface of the glass tubular member of the hypodermic syringe cartridge is made rough along a strip which extends substantially the length of the cartridge.  A piece of a solid but easily abradable material is retained on the circum-ference of the rubber drive piston, and the resiliency of the rubber drive piston squeezes the abradable material against the rough strip on the inside wall of the glass tubular member.  As the drive piston is advanced to express fluid from the syringe, some of the abradable material becomes lodged in the rough surface where it remains even after the drive piston has been retracted to its original position.  In another embodiment the marking substance is a fluid, paste, or liquid which is stored in a reservoir inside the drive piston and which is squeezed out of the drive piston by the compressive forces that act on the drive piston as it is being advanced.
